Abstract

본 발명은 이중화된 시스템에서 하드웨어 기능을 최소화하고, 운용시 이중화된 기능의 부하(LOAD)를 줄일 수 있도록 하여 시스템의 이중화 기능을 안정되고 효율적으로 하기 위한 부하분담 방식의 이중화 및 절체 방법과 이를 수행하기 위한 시스템에 관한 것으로, 일반적인 이중화 방법에 사용하게 되면, 처리하는 부하에 비해서 이중화를 하기 위한 하드웨어 및 소프트웨어 기능이 많아지고, 이에 따라 제조 비용도 높아지며, 또한 상대측으로 절체시 절체시간이 느린 문제점이 발생하므로, 본 발명에서는 신뢰성, 경제성 및 절체 시간을 줄이기 위한 방법으로 양측이 액티브 상태로 동시에 동작하도록 하면서 양측이 부하를 분담하여 처리하도록 하고, 한측이 고장시 상대측이 고장난 상대측의 부하를 동시에 처리하다가 고장 상태가 복귀되면 다시 부하를 분담하여 처리하는 방법 및 시스템을 제공하여, 제조비용을 줄이고, 한측이 고장날 시 절체되는 시간을 줄여 신뢰성을 높이는 효과를 가져오게 한다.The present invention minimizes hardware functions in a redundant system and reduces the load of the redundant function in operation, thereby performing a load sharing redundancy and switching method for stable and efficient system redundancy and performing the same. It is related to the system to be used, and when used in the general redundancy method, hardware and software functions for redundancy are increased compared to the load to be processed, and thus, manufacturing cost is high, and the transfer time is slow when switching to the other side. In order to reduce reliability, economy, and transfer time in the present invention, the two sides share the load while the two sides operate simultaneously in an active state, and when one side fails, the other side simultaneously handles the load on the other side. Load again when fault condition returns By providing a method and system to share the processing, to reduce the manufacturing cost, and to reduce the time to transfer when one side breaks, it has the effect of increasing the reliability.
